In this case we will tackle each technique individually as they are each unique and of a special type:
(Suiton: Mizu Kuri No Yaiba) - Water Style: Sword of Draining
Rank: D
Range: Short
Chakra cost: 10
Damage Points: 20
Description: A technique that utilizes water to create a sword. The sword can be wielded in the normal fashion, allowing the ninja to cut and stab like with a normal blade.
Note: Doesn't require a water source.
This technique is the one that utilizes what we can call "Solid Water". Basically, it works around the principle of making water so dense, compact and compressed that it becomes solid to the touch. This solidity however is only granted by its pressure and compression and once the chakra ends, so does the water expand and resort back to liquid status. In the case of this technique, its very useful in close range.
(Kirigakure No Jutsu) - Hidding in Mist Jutsu
Rank: D
Type: Supplementary
Range: Short-Long
Chakra Cost: 10
Damage Points: N/A
Description: This displacement technique creates a thick mist to spring forth by lifting up some water from either a pre-existing source or expelled from their mouth, then goes in and out of sight at will from within the pearly-white realm. The mist's thickness is controlled by the amount of chakra kneaded into it. It can't fool the Byakugan, but, due to the mist being created with the user's chakra, any Sharingan and Rinnegan-user will see the mist coloured by their opponent's chakra, which will effectively hide the user from the dōjutsu.
Note: Can be created through releasing from mouth or manipulating a nearby water source.
(Suiton: Kirigakure Shiryoku Hakudatsu) - Water Release: Hidden Mist Eye Sight Deprevation
Rank: C
Type: Supplementary
Range: Short-Mid
Chakra cost: 15(-3 each turn to keep it active)
Damage Points: N/A
Description: Using the hidden mist jutsu the user reflects the natural light an a way that it blinds there opponent temporarily as long as the opponent is in the mist.
Note: Must have already used hidden mist jutsu
Both revolve around the usage of water release to produce or manipulate mist. Mist is, unlike water vapor or steam, simply scattered water droplets. Its cool and its still considered liquid water. Its just that the dropplets are so scattered apart that it becomes almost like a vapor. The first technique is essential to block the opponents eye sight and mainly to fight agaisnt Sharingan users. As the water droplets are infused with your chakra, it prevents the enemy from seeing you. Byakugan users will not be hindered by this nor will sensors. Wind can easily counter most of the technique. The second one is about using the water droplets to reflect light and blind the opponent. Its a simple principle.
(Suiton: Kokuun) - Water Style: Black Clouds
Rank: C
Type: Supplementary
Range: Short-Mid
Chakra cost: 15
Damage Points: N/A
Description:After performing the Ram → Snake → Tiger hand seals the user creates a flammable black mist that forms a small cloud. The user can then move the cloud above their target and disperse it, covering the target in flammable oil.
This one will be removed but until then you basically make black clouds that rain flammable oil on to the enemies. The oil can then be ignited.
(Suiton: Mizuame Nababara) - Water Style: Starch Syrup Capture Field
Rank: C
Range: Short/Long
Chakra Cost: 15
Damage Points: N/A
Description: The user After performing the required hand seals Ram → Tiger spits out high-viscosity, chakra infused water, aimed at a surface of wide scope. This is a stream of sticky liquid which can be used to form an adhesive trap that can inhibit a person's mobility. One can effectively reduce their enemy's area of activity with this technique, and has the effect of being able to take complete control over the battlefield. The normal scope of this technique is normally just a few metres, but if prepared, it is also possible to make an entire pond of starch syrup. Being caught in the technique can be avoided by channelling chakra to one's feet allowing one to walk upon it uninhibited, beforehand.
Sticky water. Basically you make a dense water that is very heavy and thick, adhesive and can be used effectively to bind your target or disable it. Not much can be said about it. Its very useful though.
